Audiometers refers to structures that are employed to test out the amount of hearing loss. These are primarily used in professional facilities, including ear, nose and throat offices and audiology places. Usually they feature embedded hardware that is attached to headphones and a test button that is controlled through a computer.

These machines may be used along with bone vibrators in an effort to check on conductive hearing units. There are software and hardware meters available in an assortment of models. The meters usually connect to computers and are operated from there. There are also versions available for at-home use. However, the accuracy of results obtained from home models is lower because there is no calibration standard in place.

Clinical models tend to provide the best, most efficient of results than other versions. They can also be more expensive. This is why these models are mostly only used in professional facilities, such as hospitals, audiology offices, research facilities and other places where there is much emphasis placed on having the most accurate and precise of results.

Devices used regularly must be calibrated on a consistent basis. This is necessary to guarantee that the level on a display is the same as the stimulus test subjects are exposed to. Furthermore, proper calibration is crucial to obtaining consistent measurements that are accurate no matter where a test is done. Reliable measurements are needed to help characterize and measure the loss of an individual. Audiometric Calibration System or ACS, and Ear Simulator System or ESS, are two devices commonly used for calibration purposes.

Audiometry is derived from Latin words meaning to hear and to measure. This practice is often defined as measuring of hearing ability. The field is primarily concerned with checking hearing ability and different levels and checking the ability of one to distinguish between varying sounds, pitches and intensities. These devices are also used for otoacoustic emissions and acoustic reflex purposes. The results of tests are used by doctors to diagnose all types of ear problems.

A lot of retailers sell these items. Prices for the products will differ. Complex models that provide results with high accuracy are often more expensive and used in professional environments. There are inexpensive models that can be purchased for use at home.

Many different things can lead to hearing loss. This loss might be partial or total. The key problem is a decreased sensitivity to noises typically heard. Usually the amount of loss is based on the increase that is needed for the sound to be picked up by the hearer.

Audiometers is the term used to describe machines that are mostly used in audiometry. The units, which are available in different models, are employed for measuring hearing loss. The more complicated versions are typically more expensive but provide results that are highly accurate. For this reason, they are usually found in professional settings. At-home versions are less accurate but inexpensive and available through many retailers. Either way, regular calibration is a major factor when it comes to properly operating the units and getting results that are of the highest accuracy possible.
